More than 50% of us live in cities today and that number is growing

Before World War II, the majority of humanity lived on subsistence farms supporting large family units. Today less than one-third of humanity practices subsistence agriculture. Evidence shows that as populations resettle in cities, family size decreases while average lifespan increases.

Mass urbanization, therefore, is acting as a population control. As we approach cities will cause an overall slowing of the population explosion that today seems so disturbing to us. Central and Latin America are quickly approaching the same level of urbanization of North America and Europe.

It is in these two continents where rapid urbanization is happening. Our 21st century future is being shaped by cities. Half of us now live in cities and the rate of increase in city dwellers is approaching 70 million per year. Instead so many of these fast-growing urban centres suffer from inadequate funding, poor services, congestion and the growth of informal economies that contribute nothing to the tax base necessary for 21st Century Urban Landscape Journal funding urban improvements.

These are the urban realities of the 21st century where humanity needs to come to terms with new ways of achieving sustainability. It is in these cities that humanity will experience the bulk of urban growth. With urban migration amounting to people per minute, the cities of these parts of the world face immense new challenges.

For most new migrants to cities in the first decade of the 21st century they experience urban environments like the one in the picture below. Over 1 billion urban dwellers live in what best can be described as slums although slums in the Developed World look posh compared to what is depicted here.

The informal economy is huge. But it is an economy that is underground, driven by barter and cash. It makes no tax contribution to the cities in which it operates. As a result the cities have inadequate funding to provide improved services and materials to the newcomers who desperately need what the city potentially can offer. This Jakarta slum sits on the edge of the modern downtown and is an example of what is occurring through much of the Developing World with the rapid migration of rural populations to urban settings.

Source: The Telegraph. A good example of this dynamic can be found in Lagos, Nigeria. A slum there, called Makoko, is home to rural fisherman who have migrated to pursue the dream of a better life.

The inhabitants find jobs wherever they can, develop home-based business ventures, barter for food and material goods, contribute to the survival of their families but have no economic relationship with Lagos itself. Makoko is like many African urban slums. Its people are disenfranchised with no property they can call their own. They have limited city services. Almost everything of use is found by residents foraging for materials, and finding sources of power and water when and wherever possible.

And should the Government of Nigeria choose to build something in Makoko these homes get bulldozed with the tenants having no legal title or recourse. Lagos is the fastest growing city in Africa. Makoko represents one of its many enormous challenges. Two-thirds of its inhabitants will reside in Makoko-like shanty towns. In Lagos will become the 3rd largest city in the world, only surpassed by Tokyo, Japan with its well-developed infrastructure, and Mumbai, India, suffering from many of the same challenges as Lagos.

When informal settlements mushroom into existence almost overnight and usually within proximity of the commercial centres of these cities, what can planners do to deal with these new facts on the ground?

Today 1 billion people live in urban slums. Total new annual housing requirements equal 35 million units per year, 96, per day, 4, an hour, or 66 per minute.

The United Nations Population Fund , an international body Landscape Light Bulb Replacement Company focused on the challenges of population growth in cities is seeking international cooperation to develop innovative housing policies.

One idea changes informal settlements, Urban Landscape Photographers Uk 50 such as the one depicted in Jakarta, into planned communities where new immigrants have significant input. The idea is to encourage new immigrants to build permanent homes by providing Floors 2000 Urban Landscape Zoom simple, easy-to-construct plans along with appropriate building materials. House designs would allow for family expansion. Instead of horizontal growth, houses would grow vertically allowing families to safely add 2nd and 3rd floors over time.

This would address the need for urban intensification without building of high-rise concrete towers. It would also allow families to operate informal businesses from their homes, a reflection of the cultural characteristics of newcomers and the informal economy in which they operate. Another idea comes from Venezuela where squatter settlements around the capital city, Caracas, are undergoing transformation. Instead of demolishing these shanty towns and moving the inhabitants to high-rises, urban planners are surveying the settlements and providing those living in the area with title to the property they occupy.

Pride of ownership can work magic even in an impoverished community. This policy is leading to the formalizing of these suburbs and their integration into the larger urban community including the provisioning of city services.

Venezuela is also experimenting with novel building materials to meet its growing demand for new housing. Because the country has abundant oil reserves, it is manufacturing homes from the output of refineries and even exporting these simple, modular plastic homes to other Developing World countries like Cuba. Looking remarkably like any suburban bungalow, these Venezuelan-built plastic homes are a novel approach to meeting housing demands of cities in the Developing World.

For the people of Lagos and other Developing World cities, experiments in policy such as those described above could prove to be powerful new methods for changing the urban environment. After all, Nigeria and Venezuela share the same challenges and both have abundant oil reserves.
